摘　　要：我国北方地区既有非节能居住建筑高能耗问题突出,既有非节能居住建筑节能改造十分必要。以严寒地区典型城市既有非节能居住建筑为研究对象,对2015—2016年、2016—2017年采暖季(节能改造前、后)换热站、二次输配管网及建筑本体三处节点进行采暖能耗实测,掌握不同改造内容对节能量的贡献率。通过将换热站及二次输配管网的实际能耗水平与标准规范值进行对比得出各项改造技术的节能贡献率;结合建筑本体的实际改造效果对改造前后的建筑仿真模型依次进行修正,模拟得到建筑本体各项改造技术的节能贡献率。结合改造技术的经济性核算,获得各项改造技术的经济贡献率及静态回收期,为建筑节能改造的相关政策制定与市场化推广提供依据。Given the high energy consumption of non-energy-saving residential buildings in northern China,it is necessary to implement energy-saving renovation in such residential buildings.The non-energy-saving residential buildings in typical cities in severe cold regions are selected as the object of study.The heating energy consumption at the three nodes including heat exchange stations,secondary distribution pipe networks and building was measured in the 2015-2016 and 2016-2017 heating seasons(before and after energy-saving renovation).The actual energy consumption level of heat exchange stations and secondary distribution pipe networks was compared with the standard value to obtain the energy-saving contribution rate of each renovation technology.The building simulation model before and after renovation was corrected in turn according to the actual renovation effect of building to obtain the energy-saving contribution rate of each renovation technology.The economic contribution rate and static recovery period of each renovation technology were finally determined by referring to the auditing results of renovation technology.The findings can provide a basis for policy formulation and market promotion of energysaving renovation.
